My mobile number is a prime number

What is a prime number?$

Any integer p greater than 1 is called a prime number if and only if its positive factors are 1 and the number p itself.
In other words, the natural numbers which are completely divisible by 1 and themselves only and have no other factors, are called prime numbers. 2$ ,$ 3$ ,$ 5$ ,$ 7$ ,$ 11$ ,$ 13$ ,$ 17$ ,$ 19$ ,$ 23$ ,$ 29$ …$ $ $ $ etc. are prime numbers [or just Primes]. The numbers greater than 1, which are not prime are called Composite numbers.
